Linux – Automount sshfs using fstab without mount -a

fuselinuxsshsshfsUbuntu

Please consider following fstab line (line breaks for readability):

sshfs#user@192.168.1.123:/home/user/ 
/home/user/Server/ 
fuse    
auto,user,_netdev,reconnect,uid=1000,gid=1000,IdentityFile=/home/user/.ssh/id_rsa,idmap=user,allow_other  
0

It works fine, but every reboot I need to use mount -a to mount the server (or click appropriate icon in Thunar to mount the thing)

Is it possible to mount my ssh directory straight-away on boot time?

I am using Xubuntu 13.10

The correct syntax for mounting sshfs shares at boot, in the /etc/fstab file is

 USERNAME@HOSTNAME_OR_IP:/REMOTE/DIRECTORY  /LOCAL/MOUNTPOINT  fuse.sshfs _netdev,user,idmap=user,transform_symlinks,identityfile=/home/USERNAME/.ssh/id_rsa,allow_other,default_permissions,uid=USER_ID_N,gid=USER_GID_N 0 0

It is an adaptation to non-systemd distros of the instructions contained here. If you are instead on a systemd distro (Arch, Fedora, OpenSUSE,...), the suitable instruction is:

USERNAME@HOSTNAME_OR_IP:/REMOTE/DIRECTORY  /LOCAL/MOUNTPOINT  fuse.sshfs x-systemd.automount,_netdev,user,idmap=user,transform_symlinks,identityfile=/home/USERNAME/.ssh/id_rsa,allow_other,default_permissions,uid=USER_ID_N,gid=USER_GID_N 0 0

Short:

Check that your sshfs command works with root user.

Longer:

Check that root user has ssh identity keys setup. Mounting of sshfs through autofs uses root user for the actual mount.

This is still meant only for desktop or laptop users with a single user using these mounts!

auto.master line

note! use your own uid and gid and specify your prefered mount point I use /auto/mehtod/address

/auto/sshfs /etc/auto.sshfs uid=1000,gid=1000,--timeout=60,--ghost

auto.sshfs this is a bit more generic than just one mount

#!/bin/bash

# Shell script that acccepts one argument, namely userid@server
# env >> /tmp/env_check
# whoami >> /tmp/env_check

key=$1
USER='your_local_user_used_for_ssh_identity_file'
REMOTEDEFAULT='default_to_this_user_otherwise_root'
key=${key//[: #]/}

# add user
[[ ! "$key" =~ "@" ]] && key="${REMOTEDEFAULT}@${key}"

case $key in
   ${REMOTEDEFAULT}@.Trash*)
      exit 1;;
   *)
      (
      echo "-fstype=fuse,idmap=user,rw,nodev,nonempty,transform_symlinks,noatime,allow_other,IdentityFile=/home/${USER}/.ssh/id_dsa,max_read=65536\\"
      echo -e "\t /uhome :sshfs\#$key\:\\"
      echo -e "\t /tmp :sshfs\#$key\:\/tmp\/\\"
      echo -e "\t /rootfs :sshfs\#$key\:\/")
esac

## this is a bit more complex. It creates subfolders to autofs-mount/remotename
## /uhome  = your remote homedirectory
## /rootfs = remote root '/'
## /tmp    = remote tmp # same as /roots/tmp

then link to folder you want to access ln -s /auto/sshfs/userid@my.remote.example.com/uhome/ remote-home
